对8例老年女性和1例中年男性的可逆壶腹样左心室造影的临床病理表现进行了研究。7例心电图ST段抬高的患者冠状动脉造影正常。在接受刺激休息的7名患者中，只有2名患者冠状动脉痉挛呈阳性。活检标本显示局灶性心肌细胞损伤。ST段抬高时正常的冠状动脉造影和病理心肌损害的存在与顿抑心肌的概念不一致。心肌损害的存在表明已经发生了局灶性和弥漫性心肌损害。
The clinicopathologic findings of reversible ampulla-like ventriculogram of the left ventricle were studied in 8 elderly women and one middle-aged man. Their coronary arteriograms were normal, even in the 7 patients who had ST elevation on electrocardiogram. Coronary spasm was positive in only 2 of the 7 patients who received provocation rests. Biopsy specimens revealed focal myocyte injury. Normal coronary arteriograms during ST elevation and the presence of pathologic myocardial lesions were not consistent with a concept of stunned myocardium. The presence of myocardial lesions suggested that focal and disseminated myocardial damage had occurred.
